Thank you Jack for replying

Answer 6

\[-18x^3=-32x\]
\[18x^3=32x\] b/c the negatives cancel out.
\[18x^2=32\] b/c you can divide an x from each side
\[9x^2=16\] b/c you can factour out the common term, 2
\[x^2=\frac{ 16 }{ 9 }\]
\[x=\sqrt{\frac{ 16 }{ 9 }}\]
\[x=\frac{ 4 }{ 3 }\]

Answer 20

Ok just making sure

Answer 21

i'am writing the answer ,dont worry

Answer 22

-18x^3+32x=0 . ====>We will take a common factor which is -2x .
-2x (9x^2+16) ====> now lets factorize the bracket .
-2x (3x-4) (3x+4) ====> now lets equal each bracket to zero and get the value.
-2x=0 , x=0
3x-4=0 , 3x=4 , x=4/3
3x+4=0 , 3x=-4 , x=-4/3
Therefore S.S= { 0,4/3 ,-4/3}
